「Git」- 对大文件进行版本控制(LFS, Large File Storage)

  CREATED BY JENKINSBOT

问题描述

在我们的某个仓库中,存在大量 PDF 文件,我们会频繁操作这些文件。

在提交时,Git 会进行系列操作(比如创建对应的 BLOG 文件),都会消耗很多系统资源。

在笔记将记录:在 Git 中,如何管理大文件,以及常见问题解决方案。

解决方案

GitHub 开发 Git LFS 插件来管理大文件,所以我们使用 git-lfs 来管理这些大文件。

安装插件

# Ubuntu 21.04 TLS
apt-get install git-lfs

参考 Installation · git-lfs/git-lfs Wiki 文档,获取其他系统的安装方法。

简单示例

#1 You only need to run this once per user account.
git lfs install

#2 
git lfs track "*.psd"
git add .gitattributes

#3
git add file.psd
git commit -m "Add design file"
git push origin main

常见问题处理
